SF6 gas insulated Combined transformers

Instruction

The combined transformers combinate the characters of inductive voltage transformer and inductive current transformer, and it also has the function of current transformer and voltage transformer. The insulation material is SF6 gas. The bushing of the instrument transformer is made by silicon rubber or porcelain

The combined instrument transformer shall be suitable for measurement control and relay protection in the outdoor AC power system of nominal voltage 72.5~550kV, and frequency of 50 or 60Hz.

Service Conditions

a. Ambient air temperature: maximum 40℃, minimum -40℃, average value of the ambient air temperature does not exceed 30℃ measured during a period of 24h.

b. Altitude: The altitude does not exceed 1000m (this is the routine requirement, if there is any different requirement, we can provide the products with 2000m, 3000m, 4000m or 5000m altitude according to the clients’ requirements)

c. The average value of the relative humidity does not exceed 95% at 25℃ measured during a period of one month

d. The maximum wind speed does not exceed 34m/s

e. Earthquake intensity does not exceed 8 degree

f. There have to be no gas that may seriously affect the insulation and conductive ability of electric equipments, steam, ash, salt, chemical deposit, pollution and corrosive or explosive material.
